2.5mm Pitch Board to Board Vertical Post Header MDF14A Series ■Features 1. Service Efficiency Up contact and contact. The post header is developed in the special design capable of vertically connecting the board unnecessary for insertion or extraction. The post header can be connected in combination of the receptacle with the plug at low cost. 2. Current Capacity [5A] By adopting the 0.8mm round pin as the post pin, the pin strength can be enhanced as well as the current capacity can be maintained at 5A approximately. 3. Board Pre-fixed Mechanism The kink process is provided for the board pre-fix process. 4. Pin Extraction Specification The post header corresponds to individual pin extraction specifications. ■Applications Various power supply units, and secondary power unit for the set B136 Kink process ■Product Specifications Rating Current rating : 5A Operating Temperature Range: -30 to +85ç (Note 1) Storage Temperature Range: -10 to +60ç(Note 2) Voltage rating : 250V AC Operating Moisture Range: 40 to 80% Item Storage Moisture Range: 40 to 70% Specification (Note 2) Condition 1.
